WKS Evo Circle PRO 6.5 kVA 48V hybrid inverter
The most advanced hybrid solar inverter of its generation
The WKS Evo Circle PRO is a state-of-the-art hybrid inverter designed for stand-alone and hybrid solar installations. It combines three essential functions in a single device: pure sine wave inverter, MPPT solar charge controller and mains charger. This all-in-one architecture greatly simplifies the design and management of a photovoltaic system, while guaranteeing high energy efficiency and exceptional reliability.
The WKS Evo Circle PRO stands out for its versatility, advanced connectivity and ability to operate in parallel for cumulative outputs of up to 39 kW.
This model is ideal for off-grid housing, hybrid systems with batteries, or industrial and tertiary installations requiring a reliable, continuous power supply.
An all-in-one UPS for energy independence
Designed to meet the needs of residential, professional or isolated installations, the WKS Evo Circle PRO provides a stable, clean and continuous power supply, even without an electricity grid.
Thanks to its 120 A MPPT technology and wide photovoltaic input range (90 V - 450 V), it makes the most of the solar energy available, guaranteeing efficiency of over 93%.
Its dual output system allows critical and secondary loads to be managed separately: your essential appliances remain powered, while non-priority loads are activated only when there is sufficient solar production.

Installation adviceGood ventilation is essential to ensure correct heat dissipation. We recommend using cables with a suitable cross-section and protection (DC circuit breakers, fuses, surge protectors) appropriate to the power of the installation. Our technical teams can help you with the initial set-up and commissioning. |
1. Practical use - Example of a real installation
Example: Self-sufficient house with lithium batteries
An isolated 120 m² house, equipped with :
- 12 x 450 W solar panels (i.e. 5.4 kWp),
- 1 WKS Evo Circle PRO 6.5 kVa inverter,
- a battery bank with two 10 kWh Lithium Delong or Pylontech batteries.
The system works as follows:
- During the day, the WKS Evo Circle PRO converts solar energy directly to power the house and recharges the battery via its 120 A MPPT regulator.
- At night, it automatically switches to battery mode and continues to power essential equipment (lighting, fridge, freezer, telecommunications).
- In the event of a low battery or high power consumption, the integrated AC charger is triggered and recharges the batteries via the generator or the grid.
The result:
- 100% autonomy for most of the year,
- electricity bills cut by over 80%,
- no power cuts, even in isolated locations.
